Abstract [en]

INTRODUCTION: Cesarean section (CS) carries a substantial risk of maternal near-miss (MNM) morbidity. This study aimed at determining the frequency, causes, risk factors, and perinatal outcomes of MNM at three university hospitals with a high rate of CS in Tehran, Iran.

MATERIAL AND METHODS: An incident case-control study was conducted from March 2012 to May 2014. The modified WHO near-miss criteria were used to identify cases. A control sample of 1024 women delivering at the study hospitals was recruited to represent the source population. Near-miss ratio, crude and adjusted odds ratios (aORs) with confidence intervals (CI) were assessed.

RESULTS: Among 12 965 live births, 82 mothers developed near-miss morbidities and 12 died. The MNM ratio was 6.3/1000 live births. Severe postpartum hemorrhage (35%, 29/82), severe pre-eclampsia (32%, 26/82), and placenta previa/abnormally invasive placenta (10%, 8/82) were the most frequent causes of MNM. Women with antepartum CS (aOR 7.4, 95%CI 3.7-15.1) and co-morbidity (aOR 2.3, 95%CI 1.4-3.8), uninsured Iranians (aOR 3.4, 95%CI 1.7-7.1) and uninsured Afghans (aOR 4.7, 95%CI 2.4-9.2) had increased risks of near-miss morbidity. Stillbirth and extremely preterm birth were the most prominent adverse perinatal outcomes associated with MNM.

CONCLUSION: Overutilization of CS clearly influenced the causes of MNM. A lack of health insurance had a measurable impact on near-miss morbidity. Tailored interventions for reducing unnecessary CS and unrestricted insurance cover for emergency obstetric care can potentially improve maternal and perinatal outcomes.
